MECHANICALLY-OPERATED ROAD-MAP.

Specification of Letters Patent. Patented June 10, 1913.

Application filed September 8, 1909. Serial No. 516,779.

To all whom it may concern: v

Be it known that I, MAX BRnMsY, a cit-1- zen of the United States, and resident of New Rochelle, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Mechanically-Operated Road-Mapsrof which the following is a specification.

With the advent of rapidly moving vehicles designed to travel upon the ordinary roads' or highways, at the Will and under the guidance of the operator, the necessity for carefully planned andmeasured maps asserted itself, and map makers in general have given a great deal of attention and care to the production of a class of guides the box A as well as the cover may be made i called road maps.

' eight miles of roadway and four miles hori-- .This device is intended to considerably assist the driver of an auto-car in traveling any roadway or course with which he is unfamiliar."

It consists of a guide and a mechanism for operatingthe same.

I My apparatus arranges so that the ma shall travel slowly but continuously, an shall present to: the view of the operator his exact position on the road, with only sufiicient of the adjacent territory to allow him to recognize and memorize the course for future use. v V

I employ a water tightcasing for retaining the map in its position and I employ a simple mechanism. connected preferably by a flexible shaft to one of the' wheels of the vehicle, and in the best development of my device I have illuminating means within the casing for use at night.- I present a surface of map under a glass of about eight square inches, and as I have designed and timed my apparatus this will show to the operator 'zont-ally, or in all thirty two square miles of territory and I locate the operators position centrally within this large tract.

Other. advantages of my invention and means for securing them will develop as the specification roceeds'. The following f means of carrying out this invention.

The accompanying drawings form a part of this specification.

Figure 1 is a plan View of my apparatus.-

Fig. 3 is a side elevation partly in horizontal section on the llne 33 in Fig. 1. Fig. 2 is a plan view, the cover, sides and map havis what I consider the besting been removed to expose to View the interior mechanism. Fig. 4; shows in detail the driving ;mecl1anism.' Fig. 5 shows on a larger scale one of the bearing blocks for the rolls and the roller shaft socketed therein, this figure-is partly in section.

Similar letters of reference indicate like.

of brass or any suitablematerial preferably metal, but should be firm and water tight in construction.

The operating mechanism'bearings, etc.,

are secured to the inner side of the bottom of the cabinet. Brackets C, C, C C serve as bearings for the map rollers D, D. A slide E operable from the outside by the knob E carries sprockets E andcut gears Each sprocket E is'securely attached to an adiacent gear E. A flexible shaft F connected by suitable means with one of the wheels of the automobile, has its upper end extending within the casing A, and carries on the upwardly extending end a worm-gear F which meshes with a worm-wheel F Securely attached to the worm-wheel F is a cut-gear F so arranged that the operation of the knob IE will cause the slide E to bring one of the cut-gears E in mesh with the cut-gear F .for a purpose which shall appear later. A sprocket wheel C, on a shaft C is rotatably mounted in the bearing bracket C insuch a manner as to bring the axis of the sprocket C in line with the axis of the roll D. A chain G connects the two' sprockets C*, C together and in doing so is caused to mesh reliably with each of the sprockets E The inner end of the shafts each of the rollers D is s uaredto the sockets in the shafts C.

A series of maps covering any desired por- C are socketed and one end ofthe shaft of fit one of tion of a countrys highways are rolled upon rollers similar to those indicated byD, and

when my device is placed in operation a roller containin a map is placed in one of the .pairs 0 bearing brackets O, C, 0

An empty rol by having the squared end slipped through the hole in the bracket (1, and 'socketed 1n the shaft 0*. The bearingin the bracket 0 is an open top bearing and the roller D can be easily dropped into its position there. er now being in lace in the other bearings G, C, the end of the map 'is attached thereto, and if the knob E is not in the central position or opposite the mark indicated by 0, it should be now placed there. T The rollers'are operated to. allow the map to expose to view that portion of the road desired. The cover A isnow closed down and if the operator has so adj sted the map, the button- E can be pushed in position with the result that any movement of the wheels-of the automobile will cause the map to move in its roper direction.

The button E per orms an important function which itis possible I have not yet made plain, that is in traveling from one town to another the button is pushed in a forward posit-ion, and it will indicate, if all things are properly"adjusted, the route in going to that town. When itis desired to return over the same road the button E is placed in the exact opposite position and the map will run apparentlyibackward but will be found to be indicatingthe route for the return.

At a: I have shown a hair line drawn horizontally across the glass. In the most complete operation ofthe device the travelers nosition is assumed to be directly under this hair line 'or rather at the intersection of th-i line with vthe road beneath.

Modifications may be made within the scope of the appended claim without departing from the principle or sacrificing the advantages of this invention.

I have in my experiments operated this device in conjunction withother devices driven by a. flexible shaft as a- Speedometer, odometer, etc.

- 1 What]. claim and desire to secure by Letters Patent is:

A mechanically operated road map comprising a winding and a re-winding roll, a sprocket secured in operable relation with each of said rolls and an endless chain engaging both said sprockets, a driving mechanism c'omprisinga wormand a gear and worm wheel secured together and operated by means of-said worm, and a driven mecha- IllSIIl comprlslng a pair of sprockets mmesh with said-chain, and means operatively connected to said sprockets and adapted to be brought into driving engagement with said driving gear for alternately driving said sprocket-s in o posite directions.
